No matter what we do to the DNA of a fruit fly embryo, there are only three possible outcomes: a normal fruit fly, a defective fruit fly, or a dead fruit fly.
According to evolutionary biologist Thomas Cavalier-Smith, the idea that DNA contains all the information needed to make an organism “is simply false.”
Let us give some thought to the Y chromosome of Drosophila melanogaster, that engaging fly which is the bond-servant of genetics.
There are many solid, trustworthy inferences in modern science, but there are those that are not very trustworthy at all.
Don’t kick sand in the face of a wildebeest by joking that it looks like it was made by a committee. It might flex its muscles and charge.
